The classical theory of firmly attached time-mean turbulent boundary layers, exhibiting fully developed broadband turbulence, in the limit of large Reynolds numbers, Re, is extended in two ways, where the focus lies on their stability and receptivity. At first, the description of non-unique equilibrium flows having a so-called moderately large velocity deficit is generalised as weak spanwise va...

Results in the literature demonstrate that substantial improvements in the mechanical behavior of polymers have been attained through the addition of small amounts of carbon nanotubes as a reinforcing phase. This suggests the possibility of new, extremely lightweight carbon nanotube-reinforced polymers with mechanical properties comparable to those of traditional carbon-fiber composites. Motiva...

[1] We present a quasi-steady two-dimensional (axisymmetric) model of the heliospheric transport of galactic cosmic rays. The model is based on stochastic simulation techniques and includes all the modulation mechanisms that cosmic rays experience in the heliosphere: convection, adiabatic cooling, diffusion, and drifts. A special emphasis is given to the cosmic ray transport in the vicinity of ...

Usually, a hydrometeorological information system is faced with great data flows, but the data levels are often excessive, depending on the observed region of the water. The paper presents advanced buoy communication technologies based on multiagent interaction and data exchange between several monitoring system nodes. The proposed management of buoy communication is based on a clustering algor...

INTRODUCTION Glaucoma is the second leading cause of irreversible blindness worldwide with neural damage starting within the lamina cribrosa of the optic nerve head (ONH). It is known that elevated intra-ocular pressure (IOP) is the main risk factor for glaucoma, and many studies have shown that this is because glaucoma is related to a biomechanical imbalance in the eye [1]. Studies have also s...

The main task of engineering surface metrology is to characterize a surface by assessing components such as form, waviness and roughness that correspond to different wavelength segments in the frequency domain, which are often extracted by deploying filtering techniques. The effectiveness of a specific kind of filtering algorithms is jointly determined by their filtering accuracy and computatio...

A methodology was developed for the prediction of the electrical properties of carbon nanotube-polymer nanocomposites via Monte Carlo computational simulations. A two-dimensional microstructure that takes into account waviness, fiber length and diameter distributions is used as a representative volume element. Fiber interactions in the microstructure are identified and then modeled as an equiva...

The surface motif combination, ISO 12085:1996, is a method of analyzing surface texture alternatively to the central line system ‘M’. It gives a graphical evaluation of surface profile using mainly six parameters without filtering waviness from roughness. Another functional roughness characterization is introduced by the DIN 4776 and ISO 13565-2 standards through the ‘’Rk’’ parameters, which de...

Shrinkage behavior and crack formation during firing have been investigated for Al2O3/Ce-TZP composites that have been fabricated by colloidal rolling and folding. These composites show improved sinterability and sinter isotropically after repeated rolling. Interface instability in rolling creates corrugated interfaces with large layer waviness; therefore, rolling can substantially alleviate th...
